MFC r260311, r260831:
gcc: Add support for Apple's Block extension
Block objects [1] are a C-level syntactic and runtime feature. They are similar to standard C functions, but in addition to executable code they may also contain variable bindings to automatic (stack) or managed (heap) memory. A block can therefore maintain a set of state (data) that it can use to impact behavior when executed.
This port is based on Apple's GCC 5646 with some bugfixes from Apple GCC 5666.3. It has some small differences with the support in clang, which remains the recommended compiler.
Perhaps the most notable difference is that in GCC __block is not actually a keyword, but a macro. There may be workaround for this issue in the future. Other issues can be consulted in the clang documentation [2]
For better compatiblity with Apple's GCC and llvm-gcc, some related fixes and features from Apple have been included. Support for the non-standard nested functions in GCC is now off by default.
No effort was made to update the ObjC support since FreeBSD doesn't carry ObjC in the base system but some of the code crept in and was more difficult to remove than to adjust.

MFC rr258501, r258507; gcc: Bring updates from Google's enhanced gcc-4.2.1.
Google released and enhanced version of gcc-4.2.1 plus their local patches for Android[1].
The patches are owned by Google and the license hasn't been changed from the original GPLv2. We are only bringing a subset of the available patches that may be helpful in FreeBSD, in other words, changes specific to android are not included.
From the README.google file[1].
Patches applied to google_vendor_src_branch/gcc/gcc-4.2.1:
gcc/Makefile.in gcc/c-common.c gcc/c-common.h gcc/c-opts.c gcc/c-typeck.c gcc/cp/typeck.c gcc/doc/invoke.texi gcc/flags.h gcc/opts.c gcc/tree-flow.h gcc/tree-ssa-alias-warnings.c gcc/tree-ssa-alias.c
Backport of -Wstrict-aliasing from mainline. Silvius Rus <rus@google.com>
gcc/coverage.c: Patch coverage_checksum_string for PR 25351. Seongbae Park <spark@google.com> Not yet submitted to FSF.

Ollie Wild <aaw@google.com>. Submitted to FSF but not yet approved.
libstdc++-v3/include/ext/hashtable.h http://b/742065 http://b/629994 Reduce min size of hashtable for hash_map, hash_set from 53 to 5
libstdc++-v3/include/ext/hashtable.h http://b/629994 Do not iterate over buckets if hashtable is empty.
gcc/common.opt gcc/doc/invoke.texi gcc/flags.h gcc/gimplify.c gcc/opts.c Add Saito's patch for -finstrument-functions-exclude-* options.
gcc/common.opt gcc/doc/invoke.texi gcc/final.c gcc/flags.h gcc/opts.c gcc/testsuite/gcc.dg/Wframe-larger-than.c Add a new flag -Wframe-larger-than- which enables a new warning when a frame size of a function is larger than specified. This patch hasn't been integrated into gcc mainline yet.
gcc/tree-vrp.c Add a hack to avoid using ivopts information for pointers starting at constant values.
